Introduction In certain hazardous situations, PRE-SAFE
®
takes pre-emptive measures to protect the vehi-
cle occupants.
Important safety notes !
Make sure that there are no objects in the
footwell or behind the seats. There is a risk
that the seats and/or the objects could be
damaged when PRE-SAFE ®
is activated.
Although your vehicle is equipped with PRE-
SAFE ®
, the possibility of injury in the event of an
accident cannot be ruled out. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under- steers or oversteers severely
R when active Brake Assist intervenes power-
fully
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the side windows and the
panorama sliding sunroof are closed.
R vehicles with the memory function: the front-
passenger seat is adjusted if it is in an unfav-
ourable position.
If the hazardous situation passes without result- ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back slightly
when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" (Y page 43). Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact: R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R the engine is switched off and the fuel supply
is cut off

RefuellingDriving and parking
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes Trailer towing is not possible on the following
models:
R CLA 180 d BlueEFFICIENCY Edition
R CLA 250 Sport
R CLA 250 Sport 4MATIC
R Mercedes‑AMG CLA 45 4MATIC
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 313).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.
R Parking Assist PARKTRONIC (Y page 177)
R Blind Spot Assist (Y page 192)
The height of the ball coupling changes with the
load of the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 334).
Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 72).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle. If you utilise any of the added maximum rear axle load when towing a trailer, the vehicle/
trailer combination may not exceed a maximum speed of 100 km/h for reasons concerning the
operating permit. This also applies in countries
in which the permissible maximum speed for
vehicle/trailer combinations is above
100 km/h. When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift into a lower gear in good time on long and steep downhill gradients. For vehicles with auto-
matic transmission, you need to have selected
manual drive program M(Y page 150).
This also applies if you have activated cruise
control, SPEEDTRONIC or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you need additional braking, depress the brake pedal
repeatedly rather than continuously.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive pro-
gram Mis temporarily activated (vehicles with
automatic transmission): the automatic trans-
mission may switch back to the last active auto-
matic drive program Eor S. The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances
X Do not countersteer
X Brake, if necessary 196

WARNING
If wheels and tyres of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tyres with those
that fulfil the specifications of the original
part.
When replacing wheels, make sure to fit the
correct:
R designation
R type
When replacing tyres, make sure to fit the

WARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations Further information regarding wheels and tyres
can be found under "Wheel/tyre combinations"
(Y page 323).
You can ask for information regarding permitted
wheel/tyre combinations at a Mercedes-Benz
Service Centre.
Information on tyre pressures can be found:
R in the tyre pressure table in the fuel filler flap
(Y page 154)
R under "Tyre pressure" (Y page 313)
Modification work on the brake system and
wheels is not permitted. The use of spacers or
brake dust shields is not permitted. This inva-
lidates the general operating permit for the vehi- cle.
i Further information on wheels and tyres can
be obtained at any qualified specialist work-
shop. Operation
Information on driving
Check the tyre pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tyres are damaged. If you suspect that a tyre is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tyres for damage. Hidden
tyre damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tyres and wheels checked at a qualified specialist workshop.
When parking your vehicle, make sure not to
squash the tyre. If you cannot avoid driving over
obstacles, e.g. kerbs, do so slowly and at an
obtuse angle only. You could otherwise damage the wheel rims and tyres. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident. 310

message is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
After an emergency spare wheel has been fitted,
the system may still display the tyre pressure of the removed wheel for a few minutes. If this
occurs, note that the value displayed for the
position where the spare wheel is fitted is not
the same as the current tyre pressure of the
emergency spare wheel.
Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is
shown in the multifunction display. The yellow
tyre pressure warning lamp then lights up:
R If the Please correct tyre pressure

the tyre pressure in at least one tyre is too
low. The tyre pressure must be corrected
when the opportunity arises.

Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 239).
If the position of the wheels on the vehicle is
changed, the tyre pressures may be displayed in the wrong positions for a short time. After a few
minutes of driving, this is rectified and the tyre
pressures are displayed in the correct positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values for monitoring. In most cases, the tyre pressure
monitor will automatically detect the new refer- ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values. X
Use the table on the inside of the fuel filler flap
to ensure that the tyre pressure is set cor-
rectly in all four tyres for the current operating conditions.
Also observe the notes in the section on tyre
pressures (Y page 313).
